摘　　要：利用已有标准样品的活度值和放射性活度计测量得到的电流值,在不同能量段对核素分段构造函数,拟合出灵敏度曲线。然后利用灵敏度曲线函数计算出待测核素的电流活度比,从而很好地解决了HD-175型放射性活度计的刻度问题。The paper describes the sensitivity curve measurements and applications for radioactivity meter. The energy-dependent sensitivity curve is established with the activity of standard sources and their corresponding current by constructing functions subsection. Thus the current-activity ratio is acquired from the sensitivity curve and the calibration of radioactivity meter is solved satisfactorily.
